Supernatural Effect
According to the Old Testament, the rainbow was created by God after the Flood. In the biblical narrative, this would appear as a sign of the divine and to remind people of the promise made by God to Noah that He would never destroy the earth with a flood.
I have set my bow in the cloud, and it shall be for a token of a covenant between me and the earth. And it shall come to pass, that when you bring a cloud over the earth, that the bow shall be seen in the clouds. And I will remember the covenant, which is between me and you and every living creature of all flesh; and there will be no more flood of waters to destroy all flesh.
Genesis 9:13-15. 1960 Reina-Valera Bible
For this reason also the rainbow is the Noajida modern symbol of the movement as it symbolizes the covenant that God made with Noach and his descendants forever, which would have its maximum expression in the implementation of the Seven Laws of the Children of Noach.
The image of God and his throne is related in the Bible with the glory and beauty of the rainbow that appears after a storm and the sensation of peace that this produces. In the vision that Ezekiel had of God, the prophet saw "something like the appearance of the bow that occurs in a mass of clouds on the day of a strong rain", one aspect of the vision with which highlighted "the glory of the Lord". (Ezekiel 1:28.)
